Yuntai Mountain on the sea includes Da, Erjiajian, Dongyawu, Maple Bay, Baojiashan Reservoir and so on. Dongya House has a special meaning for me. Grandma's house is at the foot of the mountain. From childhood, I often climb and play. I still seem to hear the frogs in the evening, and I can smell the unique earthy atmosphere of the countryside. Every time I revisit the old place, I can trace my lost childhood. My mother was personally involved in the excavation of Baojiashan Reservoir, and often told me about the difficult and proud construction years. I used to hear adults say that you can reach Lianyungang Port by crossing Yuntai Mountain. I always jumped to try it, but my family disagreed. Now I can do it. From Maple Bay straight up to the tip of the second, then to the tip of the big tip, Lianyungang Port is in the eyes. The port, cargo ship, sea, blue sky and white clouds are intertwined beautifully. When you go down the mountain, then walk the back of the mountain until Lianyungang Old Street, the old house full of vegetation, the streets covered with bluestones, and the old buildings full of the style of the Republic of China.
